Understanding Your Needs for a Radio Scanner Car Mount
Before diving into specific mounting types, it’s crucial to consider your individual needs. What type of vehicle do you drive? What are your primary listening interests – VHF, UHF, or specific frequency bands like those used by railroads? Are you concerned about aesthetics, ease of installation, or maximum signal reception? Answering these questions will guide you to the most suitable radio scanner car mount for your situation.
Top Radio Scanner Car Mount Options
Based on expert opinions and practical experiences, here are the most effective car mount options for your radio scanner antenna:
Magnetic Mount Antennas: Convenience and Portability
Magnetic mounts are a popular choice due to their ease of installation and removal. They require no drilling and can be quickly attached to and detached from your vehicle’s roof or trunk. This is particularly useful for those who don’t want a permanent installation or who frequently switch vehicles.
Pros:
- Easy Installation: Simply place the magnetic base on a metallic surface.
- No Drilling Required: Protects your vehicle’s paint and body.
- Portable: Easily moved between vehicles or removed for storage.
- Good Performance (with proper setup): Especially effective when tuned to specific frequency ranges.
Cons:
- Cable Management: Running the antenna cable into the vehicle requires careful routing to avoid damage, often through a window or door jamb. Avoid slamming the cable in doors, as this can damage it over time. Running it through a window slightly ajar is a common practice.
- Potential for Movement: In high winds or at high speeds, magnetic mounts can sometimes shift or even detach, especially smaller or weaker magnets.
- Ground Plane Dependency: Magnetic mounts rely on the vehicle’s metal body for a ground plane. The size and location of the mount can affect performance.
Best Practices for Magnetic Mounts:
- Choose a Quality Antenna: Invest in a magnetic mount antenna specifically tuned to your desired frequency range (e.g., 160-162 MHz for railroad frequencies).
- Cable Care: Handle the cable carefully to prevent damage. Avoid sharp bends and protect it from being pinched or crushed.
- Placement: Position the mount in the center of the roof if possible for optimal omnidirectional reception. The rear of the roof is also a viable option, especially if you anticipate carrying cargo on the roof.
Permanent Roof Mount Antennas: Optimal Performance
For the best possible reception, a permanent roof mount antenna is generally considered the gold standard. These mounts are drilled directly into the vehicle’s roof, providing a solid, grounded connection and the ideal antenna placement for maximum range and clarity.
Pros:
- Superior Performance: Roof mounting provides the best ground plane and antenna height, leading to optimal signal reception and transmission.
- Secure and Stable: Permanent mounts are highly resistant to movement and detachment.
- Professional Installation: Commercial radio shops can expertly install these mounts and route cables safely.
Cons:
- Requires Drilling: Permanent modification to your vehicle’s roof.
- Professional Installation Recommended: Proper installation is crucial to prevent leaks and damage.
- Less Flexible: Not easily removed or moved to another vehicle.
- Potential Garage Clearance Issues: Taller antennas may pose a problem in garages or low-clearance areas. Consider flexible “flexi-whip” antennas to mitigate this.
Installation Tips for Permanent Roof Mounts:
- Consult Professionals: Seek advice and installation services from a reputable commercial radio shop. They have the expertise to determine the best location and routing for your antenna and cable.
- Cable Routing: Ensure the cable is routed carefully to avoid airbags and other vehicle components.
- Antenna Type: Choose an antenna appropriate for your frequency range. For VHF/UHF scanners, a unity gain or low gain antenna is often suitable for general purpose scanning.
Trunk/Hatchback Mount Antennas: A Compromise Solution
Trunk or hatchback mounts offer a compromise between the convenience of magnetic mounts and the performance of permanent roof mounts. They attach to the edge of your trunk or hatchback, providing a more permanent and robust solution than magnetic mounts without requiring drilling into the roof.
Pros:
- More Secure than Magnetic Mounts: Clamps or bolts provide a more stable attachment.
- No Roof Drilling: Avoids permanent modification to the roof.
- Good Performance: Can offer better performance than magnetic mounts, especially when properly grounded.
Cons:
- Installation Required: Typically requires some level of installation, though less invasive than roof mounts.
- Cable Routing: Cable routing needs careful consideration, often through the trunk or hatchback opening.
- Placement Limitations: Location is limited to the trunk or hatchback edge, which may not be as optimal as a central roof location.
Popular Trunk Mount Options:
- Diamond K400S: A well-regarded trunk lip mount known for its versatility and ease of installation. It allows for mounting on various vehicle hatch and trunk configurations.
Inside Vehicle Antennas: Discreet but with Performance Trade-offs
Inside vehicle antennas, such as window-mounted or dashboard antennas, offer the most discreet option, as they are installed entirely within the vehicle. However, they typically come with performance sacrifices compared to external antennas.
Pros:
- Discreet Installation: Antenna is hidden inside the vehicle.
- Easy Installation: Often use adhesive or suction cups for mounting.
- No Exterior Modifications: Preserves the vehicle’s external appearance.
Cons:
- Reduced Performance: Being inside the vehicle cabin significantly attenuates radio signals, especially VHF signals. Performance can be significantly less than external antennas. Expect to lose half or more of the signal strength compared to an external antenna.
- Not Ideal for Weak Signals: Best suited for receiving strong, local signals. May struggle with weaker or distant transmissions.
- “Through-the-glass” antennas: These types also suffer performance loss compared to external mounts.
Considerations for Inside Antennas:
- Proximity to Window: Mount the antenna as close to the window as possible to minimize signal attenuation.
- Frequency: UHF signals may perform slightly better than VHF inside vehicles due to shorter wavelengths, but performance will still be compromised.
Key Considerations for Choosing a Scanner Antenna
Beyond the mount type, the antenna itself plays a crucial role in your scanner’s performance. Here are some key antenna considerations:
- Frequency Range: Select an antenna that covers the frequency bands you want to monitor (VHF, UHF, 800 MHz, etc.). Tuned antennas optimized for specific bands (like 160-162 MHz for railroads) can offer superior performance in those ranges.
- Antenna Gain: Higher gain antennas can improve reception of weak signals but may have a narrower coverage pattern. Unity gain or low gain antennas are often preferred for general scanner use.
- Antenna Length: Antenna length is related to the wavelength of the frequencies you want to receive. Longer antennas are generally more effective for lower frequencies (VHF), while shorter antennas are suitable for higher frequencies (UHF).
- Cable Quality (Coax): Use high-quality coaxial cable with minimal signal loss. RG-58 or better is recommended for most scanner applications. Minimize cable length to further reduce loss.
- Connectors: Ensure proper connectors for your scanner and antenna. BNC connectors are common for scanners.
Conclusion: Choosing the Best Car Mount for Your Radio Scanner
Selecting the right radio scanner car mount depends on your priorities and vehicle. For optimal performance and range, a permanent roof mount is the best choice, though it requires a more involved installation. Magnetic mounts offer excellent convenience and portability, making them ideal for temporary setups or users who switch vehicles frequently. Trunk mounts provide a good balance of performance and ease of installation. Inside vehicle antennas are the most discreet but come with significant performance limitations and are best suited for strong, local signals.
